    • InvoiceNumber of type Character String. For detailed instructions, see Step 5.4.
    • InvoiceDate of the Date type (for good quality images) and InvoiceDateAsString of type Character String (if the search for the InvoiceDate element produced no results) merged into a grDate element of type Group. For detailed instructions, see Step 5.5.
